HALOGENATED FIRE-RETARDANT COMPOSITIONS AND FOAMS AND FABRICATED ARTICLES THEREFROM

摘要

The compositions of the present invention comprise at least one substantially random interpolymer (or blends with other thermoplastics), one or more flame retardant compounds and, optionally one or more flame-retardant synergists. For levels of flame retardants which yield a halogen content of 0.05 to 50 parts-per-hundred resin (phr), depending on whether the structure is foamed or not, which in turn result in LOI levels greater than or equal to 23 percent oxygen, the compositions of the present invention unexpectedly still retain desirable mechanical properties such as compressive strength, toughness, and elasticity.
